IL-8 induces [Ca2+]itransients in human neutrophils and lymphocytes but not in eosinophils. Spectrofluorometric measurements of [Ca2+]iin Fura-2–loaded purified human eosinophils, neutrophils, and lymphocytes were performed. Cells were stimulated at the indicated time points; C5a or RANTES was used as a positive control. One representative experiment of six performed is shown.
